JOHN W. SHEAFFER, OF FRANKLIN, YORK COUNTY, PA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 288,502, dated November 13, 1883. Application filed April 2, less. (No model.)

.To all whom it may concern:

Be it known that I, JOHN WESLEY SHEAF- FER, of Franklin township, York county, State of Pennsylvania, have invented a new and. Improved Gar Coupling; and I hereby declare the following to be a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, making part of this specification, in whic Figure 1 is a perspective view of the coup: ling approaching the coupling-point. Fig. 2 is a plan view with the tops of the draw-heads removed. Figs. 3 and 4 are details to be referred to. y

My invention consists of sundry details of construction, as hereinafter described, and specifically pointed out in the claims. I

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner in which I have carried it out. I

In the said drawings, A A are the drawheads, and B B the coupling devices. These coupling devices or rods are made with barbed heads b and square bases d, the barbed ends catching over the square bases and sustained against any side throw tending to disengage them, by means of stout springs O O, which bear against the curved back of the barbed heads. The coupling-rods B B are pivoted at e e by coupling-pins f f, and their contiguous faces are made in opposite curves, 9 g and h h, joined by diagonal sectionsii. blocks D D, resting on the bottoms of the draw-heads, and moved transversely by means Sliding of levers E, pivoted to any convenient point of the platform, serves to disengage the coup- V ling-rods by their heads I Z forcing the barbed ends against springs G O, and out of contact with the square bases (1 d. In addition to the holes for pins f f, the draw-heads are supplied with the ordinary holes when the com mon coupling-link is used, so that when a car provided with my improved coupling has to couple with a car having the ordinary pin and link, pin f can be at once removed, rodB taken out, and the pin transferred to hole for that purpose, and the ordinary link-coupling used. As the cars approach their momentum forces the barbed heads by springs O to the coupling-position. When the barbed points are disengaged and the cars recede, the convoluted faces strike against each other, and prevent the barbed heads catchingeach other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. The draw-heads A A, in combination with the convoluted coupling devices B 13, substantially as described.

2. In a car-coupling, the coupling devices B B, engaging each other by means of heads b b, in combination with the transverse sliding bars D D, having heads ll, the springs O G, and levers E E, operating as described, as and for the purpose set forth.
